The beauty of digital is post processing! You can double, triple, heck even quad expose to your heart's content with photoshop: without calculating re-exposures or keeping the same frame in the camera for hours till the "part two" shot becomes available.

I have just completed a pictoral directory for our church. One of our ladies was complaining that her hair was a mess. Convinice her to have her picture taken anyway. I told her I would make her look like Liz Taylor when Liz was in her 30's. I found a photo of Liz cut and pasted the head on the ladies photo. I used Photoshop tools to blend in the skin color and it was difficult for anyone to know that it was not Liz. Digital Photography is fun.

Yes, that makes sense. try this:
1.open both images as seperate files in photoshop.
2. make the image you want to copy current by clicking on it.
3.go to tab: SELECT then click ALL
4. go to tab EDIT then click COPY
5. click on the other image to make it current
6. go to tab EDIT then click PASTE
7. the first image will be pasted onto this one on a seperate layer. go to the LAYERS window, select the layer with this new image (LAYER 2) and open the OPACITY window at the top right
8. you can adjust the slider to the desired intensity (i.e. exposure).

If you only want part of the image copied, you can do that by selecting only parts of it in step 3. Only the selected parts will be copied and pasted.

PHEW! this was the longest reply for me so far - hope it helps.

In PhotoShop there are a whole bunch of ways of getting the same results, but instead of geof's last step, "If you only want part of the image copied, you can do that by selecting only parts of it in step 3. Only the selected parts will be copied and pasted." I's suggest using layer masks. Mask out the part that you don't want to show - you can use a gray mask to let it partly show through. Different "densities" of gray in different parts to change the "exposure" of the top layer in different parts of the picture.

Harder (for me anyway) to explain how to do it than it is to actually do it.
